Great Dark Spot

NASA's Cassini imaging scientists processed this view of Saturn's moon Hyperion, taken during a close flyby on May 31, 2015.

This view is a mosaic of three images of Eros taken by NEAR Shoemaker on August 19, 2000, when the spacecraft was orbiting at about 50 kilometers (31 miles) above the asteroid.

This mosaic of NEAR Shoemaker images, taken on December 3, 2000, from an orbital altitude of 200 kilometers (124 miles), provides an overview of the eastern part of the asteroid's southern hemisphe...

The largest storm to ravage Saturn in decades started as a small spot seen in this image from NASA's Cassini spacecraft on Dec. 5, 2010 -- the same day Cassini also detected frequent lightning sign...

Occator Crater and Ahuna Mons appear together in this view obtained by NASA's Dawn spacecraft on February 11, 2017.

This artist's rendering shows Titan's surface with Saturn dimly visible in the background through Titan's thick atmosphere of methane, ethane and (mostly) nitrogen. The Cassini spacecraft flies ove...

This image of Saturn's outer A ring features the small moon Daphnis and the waves it raises in the edges of the Keeler Gap. The image was taken by NASA's Cassini spacecraft on Sept. 13, 2017. It is...

Titan may be a ''large'' moon - its name even implies it! - but it is still dwarfed by its parent planet, Saturn.

This northern hemisphere scene from NASA's Dawn spacecraft, taken on Oct. 20, 2016, features Ceres' Messor Crater, exhibiting a flow feature from the collapse of the rim of an adjacent crater.

This 1981 Voyager 2 image shows the vast Saturn ring system, as well as three small icy satellites and the shadow of a fourth. Saturn is the second largest planet in the Solar System. It has a vol...

Saturn's A ring appears bright compared to the thin F ring, which is shepherded by the moon Prometheus, in this view from the Cassini spacecraft. Prometheus can be seen near the F ring on the midd...

This frame from an animation from NASA's Dawn spacecraft shows a crater in the northern polar region of Ceres that is partly in shadow year-round, where bright water ice deposits have been observed...

NASA's Dawn spacecraft obtained this albedo image of asteroid Vesta with its framing camera on August 11th 2011.

Titan's Many Layers December 16, 2004 Full-Res: PIA06160 Cassini has found Titan's upper atmosphere to consist of a surprising number o...

This map from NASA's Dawn mission indicates the presence of hydrated minerals on the giant asteroid Vesta about 30 degrees north latitude, in August 2011. At the time, it was winter in Vesta's nort...

A pair of Saturn's moons appear insignificant compared to the immensity of the planet in this Cassini spacecraft view along the terminator where day transitions to night. The larger moon Enceladus...

This view from NASA’s Dawn mission shows the floor of Ceres’ Juling Crater. The crater floor shows evidence of the flow of ice and rock, similar to rock glaciers in Earth’s polar regions.

Researchers from NASA's Dawn mission have composed the first comprehensive views of the north (left) and south pole regions (right) of dwarf planet Ceres, using images obtained by the Dawn spacecra...

The story of the solar system is written upon the faces of its many worlds, such as Saturn's icy moon Rhea, seen here in an image from Cassini. The moon's many impact craters attest to its violent ...

NASA’s Cassini spacecraft obtained this image of Saturn’s moon Dione on Sept. 3, 2010. The camera was pointing toward Dione at approximately 49,969 kilometers (31,049 miles) away. This image has...

Shadows seem ubiquitous in this Cassini spacecraft view of Saturn's rings captured shortly after the planet's August 2009 equinox. The moon Pan (28 kilometers, or 17 miles across) casts a long sha...

This synthetic-aperture radar (SAR) image was obtained by NASA's Cassini spacecraft on July 25, 2016, during its "T-121" pass over Titan’s southern latitudes. See PIA20713 for an alternate version ...

Mosaic of Triton constructed from 16 individual images. 

Storm Alley June 11, 2004 Full-Res: PIA05405 This image shows several dark storms confined to a region below 30 degrees south lat...
